Definitions

  • This invention relates to polymers and their use as additives in crude oil, lubricating oil and fuel oil.
  • Cold Flow Improvers acts as a wax crystal modifier when blended with waxy mineral oil by modifying the size and shape of the wax crystals therein and reducing the adhesive forces between the crystals and between the crystals and the oil to permit the oil to remain fluid at a lower temperature.
  • additives are polymeric materials based on or derived from alpha-olefins, for example as described in US Patents Nos 2,895,915; 3,252,771; 3,252,772; 3,767,561; 3,790,358; 4,022,590; 4,132,663; 4,255,159 and 3,920,622.
  • EP-A-0,317,240 describes an ⁇ -olefinic random copolymer with specific physical properties comprising 70%-99.9% by weight of an alpha-olefin component having 5 to 10 carbon atoms and 0.1%-30% of an ⁇ , ⁇ -nonconjugated diene component having 6-20 carbon atoms.

  • a monomer or mixture of monomers that had been dried over a molecular sieve (1.25 moles) was added to the treated toluene drop wise over one hour, the temperature being maintained at 70°C. After 5 hours, the reaction was stopped by adding isopropanol (5 ml).
  • the molecular weight of the resulting polymers were measured by GPC (Gel Permeation Chromatography) calibrated by poly-isobutylene standards and the isotacticity by C 13 Nuclear Magnetic Resonance.
  • C6 AO, C12 AO and C14 AO designate alpha-olefin monomers where ethylene is substituted with a straight chain alkyl group having the indicated number of carbon atoms.
  • Each reference corresponds to an alpha-olefin polymer derived from the alpha-olefin monomer or monomers and in the mole percentages indicated.
  • M n is number average molecular weight and MWD is molecular weight distribution, being defined as the ratio of weight average molecular weight to number average molecular weight.
  • the polymers having reference numbers 1, 2 and 8 were each found by C 13 NMR to have isotacticities of at least 80%.
  • the other referenced polymers above would be expected to have similar isotacticities because they were prepared under identical experimental conditions.
